3) Determine if the following equation is an identity. x6 +y6 = (x2 + y2)(x4 – x2y2 + y4)
This is an identity because the equation is true.
This is not an identity because the equation is true.
This is not an identity because the equation is not true.

This is an identity because the equation is not true.

add the numbers under frequency to find the total number:

5 + 8 +7 + 4 + 0 +1 = 25

the answer is 25.

answer: the correct option is d.

explanation:

it is given that the triangle j'k'l' shown on the grid below is a dilation of triangle jkl using the origin as the center of dilation.

from the given graph it is noticed that k(4,8) and k'(2,4). let origin is defined by o and scale factor is defined by k, then

    (1)

distance formula,

put these values in equation (1).

therefore scale factor is     and option d is correct.
